Sagal Sisters: TV Stars You Know, Twins You Don't

Katey Sagal's celebrated acting career is shared by her identical twin sisters, Jean and Liz Sagal, who themselves made a notable impact on 1980s television. Born on October 9, 1961, the twins are now 65 years old. Before Katey's breakthrough role as Peggy Bundy, Jean and Liz starred as teenage sisters in the NBC sitcom 'Double Trouble' from 1984 to 1985. Their shared television career also included roles as twin cheerleaders in the 1982 film 'Grease 2' and memorable appearances in Doublemint gum commercials.

Following 'Double Trouble,' Jean Sagal continued acting in series like 'Quantum Leap' before moving behind the camera to direct episodes of popular shows such as 'Two and a Half Men.' Liz Sagal carved out a successful career as a writer and producer, contributing to shows like 'Mad About You' and 'Charmed.' Her work on 'Sons of Anarchy,' where Katey starred and her husband Kurt Sutter was the creator, brought the sisters back into a close professional orbit. The Sagal sisters grew up surrounded by the entertainment industry, with their father being television director Boris Sagal and their mother a writer.
